Seller's Comments and Description:
Take an old hose and tie it low on your fence, buildings, trees, making sure the angle goes up from where you are going to hook the water hose. After you reach a high point start tying the old hose so it angles down to above your water tank. Put a quick connect on the end of all the hoses you have wired up to your individual tanks. When you disconnect the main hose the water drains into the water tank and back out the other end. You can go from tank to tank and you will only have the one hose to drain.
This makes it easy to fill tanks in the summer too. No going thru gates. Horses are not pulling the hose out of the tanks when you are filling them.
